Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic components, in particular to an adjustable diaphragm conveying device. Background Art
[0002] The film production line obtains film products of a certain thickness by high-molecular materials such as polypropylene and polyethylene through high-temperature stretching. The polymer material sheet is first heated to above the glass temperature by high-temperature metal rollers, and then passes through the speed difference between mirror metal rollers at a certain temperature, causing the sheet to produce tensile deformation, so that the inside of the sheet obtains a consistent tendency.
[0003] In order to ensure that the diaphragm is flat on the surface of the metal roller during the production process, the tension control system will be used to control the diaphragm to enter the longitudinal pulling system with a certain tension when entering the longitudinal pulling system. Usually, the tension control methods are divided into floating roller control and tension sensor control. Both methods have certain defects. The floating roller control method uses the floating roller swing to control the diaphragm tension. When the tension changes greatly, the diaphragm will vibrate, and when the diaphragm tension exceeds the design value, it will be stuck and cause the diaphragm to break. The tension sensor method uses a pressure sensor to synchronously drive the roller speed, and controls the change of the diaphragm entrance tension by changing the roller speed. When the tension changes, the line speed of the production line will change, but when the tension fluctuates greatly, it will affect the thickness uniformity of the product. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Embodiment 1:
[0038] like Figure 1-Figure 9 As shown, the adjustable film conveying device comprises a mounting frame 1, a conveying roller 4, a driving roller 2 and a tension roller 6 are respectively mounted on the inner side of the mounting frame 1, the tension roller 6 is located between the conveying roller 4 and the driving roller 2, the film is wound on the surface of the driving roller 2 after passing through the conveying roller 4 and the tension roller 6, a motor 3 for driving the driving roller 2 to rotate is arranged on the outer side of the mounting frame 1, the motor 3 is fixedly mounted on the outer side of the mounting frame 1 by bolts, the output shaft of the motor 3 is connected to the rotating shaft of the driving roller 2 by a coupling, and a floating roller adjustment component is arranged on the inner side of the mounting frame 1;
[0039] The floating roller adjustment assembly includes two sliders 7, the cross-sections of the two sliders 7 are square, the inner wall of the mounting frame 1 is respectively provided with two slide grooves 13 for the sliders 7 to slide, the slide grooves 13 are provided with electric push rods 8 for driving the sliders 7 to slide, the two sliders 7 are respectively provided with mounting plates 9 on opposite sides thereof, the mounting plates 9 are rotatably connected with the sliders 7 through the first rotating shaft 17, a floating roller body 5 and a gravity weight 11 matched with the floating roller body 5 are rotatably provided between the two mounting plates 9, the floating roller body 5 and the gravity weight 11 are respectively located on both sides of the first rotating shaft 17, and a A mounting frame is used for installing a gravity weight 11, wherein the weight value of the gravity weight 11 is less than the weight of the floating roller body 5, and the gravity weight 11 is used to adjust the force applied by the floating roller body 5 to the diaphragm, and the diaphragm tension is controlled by swinging the floating roller body 5. When in use, the diaphragm is released by the conveying roller 4, and then is wound around the floating roller body 5 and the tension roller 6 in sequence, and then is wound around the surface of the driving roller 2. At the same time, the slider 7 can be driven to move along the slide groove 13 by the extension and retraction of the electric push rod 8, thereby driving the mounting plate 9 and the floating roller body 5 to move, and the position of the floating roller body 5 relative to the tension roller 6 can be adjusted.
[0040] Furthermore, a controller is provided on the outside of the mounting frame 1, and a tension sensor is provided inside the tension roller 6. The tension sensor is electrically connected to the controller, and the motor 3 and the electric push rod 8 are electrically connected to the controller respectively. The tension sensor feeds back the collected signal to the controller in real time, and the controller controls the roller speed of the tension roller 6, that is, the roller speed of the roller 2 is synchronously driven by the tension sensor, and the change of the diaphragm entrance tension is controlled by the change of the roller speed.
[0041] Furthermore, the two mounting plates 9 are elastically connected to one side with a first clamping member 15, and the inner wall of the mounting frame 1 is provided with a clamping groove 14 that matches the first clamping member 15 on both sides. The surfaces of the two mounting plates 9 are provided with a notch groove 10 that matches the rotating shaft of the tension roller 6. When the diaphragm needs to be wound and installed in sequence, the diaphragm needs to go around the bottom of the floating roller body 5 and then around the top of the tension roller 6 (refer to the attached manual). Figure 2 ), the winding process is more troublesome, so the staff can deflect the mounting plate 9 to a vertical state (refer to the attached manual Figure 3 ), and then it is only necessary to pass the diaphragm over the tension roller 6, and then flip the mounting plate 9 downward, so that the diaphragm is pressed under the floating roller body 5, that is, it passes under the floating roller body 5. When the mounting plate 9 is flipped upward, the first clamping member 15 will gradually align with the clamping groove 14, and then the first clamping member 15 will pop outward and be clamped into the clamping groove 14, thereby achieving the effect of preliminary positioning of the mounting plate 9.
[0042] Furthermore, it also includes an auxiliary plate 12, both sides of the auxiliary plate 12 are rotatably connected to the inner sides of the two mounting plates 9 through second rotating shafts, and a torsion spring is provided at the rotation connection. The side wall of the auxiliary plate 12 can be provided with a lifting groove for the staff to hold, and the two sides of the auxiliary plate 12 are elastically connected with second clips 16 corresponding to the first clips 15. After the mounting plate 9 is deflected to a vertical state, the staff can unfold the auxiliary plate 12 so that the auxiliary plate 12 is in a horizontal state (refer to the attached manual). Figure 3 ), the diaphragm can be installed by sliding along the upper surface of the auxiliary plate 12, so that the diaphragm can pass more easily from above the tension roller 6. When the auxiliary plate 12 is deflected to a horizontal state, the second clamping member 16 will be stuck on the mounting plate 9, thereby achieving a limiting and fixing effect.
[0043] Furthermore, the first clamping member 15 includes a countersunk hole opened inside the mounting plate 9, and a slide rod 153 is slidably provided at the smaller end of the countersunk hole, and a first clamping block 151 that cooperates with the clamping groove 14 is fixed at one end of the slide rod 153. The first clamping block 151 is a hemispherical block, and the first clamping block 151 is connected to the inner wall of the larger end of the countersunk hole through a first spring 152. The first clamping block 151 will be bounced into the clamping groove 14 under the resetting action of the first spring 152, and leave space for the second clamping member 16 to be clamped into the countersunk hole.
[0044] Furthermore, the second clamping member 16 includes an installation cavity opened on one side of the auxiliary plate 12 and a slide plate 162 slidably arranged inside the installation cavity. One side of the slide plate 162 is connected to the inner wall of the installation cavity through a second spring 163, and the other side of the slide plate 162 is provided with a second clamping block 161 squeezed by the slide rod 153. The second clamping block 161 will bounce into the countersunk hole under the action of the second spring 163 to reset. When the mounting plate 9 is flipped downward, the first clamping block 151 will be squeezed and retreated into the countersunk hole. At this time, the slide rod 153 will squeeze the second clamping block 161, so that the second clamping block 161 will withdraw from the countersunk hole, and then the auxiliary plate 12 will flip and reset under the action of the torsion spring to reset.
[0045] Embodiment 2:
[0046] like Fig.10 As shown, the floating roller adjustment assembly includes two sliders 7, the cross-sections of the two sliders 7 are square, the inner wall of the mounting frame 1 is respectively provided with two slide grooves 13 for the sliders 7 to slide, the slide grooves 13 are provided with electric push rods 8 for driving the sliders 7 to slide, the two sliders 7 are respectively provided with mounting plates 9 on opposite sides thereof, the mounting plates 9 are rotatably connected with the sliders 7 through the first rotating shaft 17, a floating roller body 5 and a gravity weight 11 matched with the floating roller body 5 are rotatably provided between the two mounting plates 9, and the floating roller body 5 and the gravity weight 11 are located at the first rotating shaft 17. On the same side of a rotating shaft 17, a mounting frame for installing a gravity weight 11 is provided between the two mounting plates 9. The gravity weight 11 is used to adjust the force applied by the floating roller body 5 to the diaphragm. By increasing or decreasing the counterweight of the gravity weight 11, the force applied by the floating roller body 5 to the diaphragm is adjusted. This is similar to the first embodiment in that the force applied by the floating roller body 5 to the diaphragm is adjusted. However, by changing the installation position of the counterweight of the gravity weight 11, it is possible to avoid one end of the floating roller body 5 from tilting upward when the counterweight of the gravity weight 11 is too large.
[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
